CHELSEA'S manager, Thomas Tuchel, has admitted to making a wrong call by bringing in Romelu Lukaku as a substitute against West Ham United.
The Belgium international had just arrived from injury but was forced into the game to replace Kai Harvetz who picked up an injury during the game.
"It’s my fault. I don’t think he is ready for 45 minutes physically but still we decided to bring him on for his height because we lost Kai, Tuchel said on Chelsea's official website.
"Kai had a crucial role in defending set-pieces, which is a huge threat from West Ham, so this is on me. I took the decision so it’s my responsibility."
Chelsea eventually lost to West Ham in a 3-2 game, which dropped them from top of the table to third place.
